200 Section 4A: Important Safety Information
Specific Absorption Rates (SAR) for Wireless Phones
The SAR is a value that corresponds to the relative amount of RF energy absorbed in the
head of a user of a wireless handset.
The SAR value of a phone is the result of an extensive testing, measuring, and calculation
process. It does not represent how much RF the phone emits. All phone models are tested
at their highest value in strict laboratory settings. But when in operation, the SAR of a phone
can be substantially less than the level reported to the FCC. This is because of a variety of
factors including its proximity to a base station antenna, phone design and other factors.
What is important to remember is that each phone meets strict federal guidelines.
Variations in SARs do not represent a variation in safety.
All phones must meet the federal standard, which incorporates a substantial margin of
safety. As stated above, variations in SAR values between different model phones do not
mean variations in safety. SAR values at or below the federal standard of 1.6 W/kg are
considered safe for use by the public.
The highest reported SAR values of the A640 are:
AMPS/CDMA mode (Part 22):
Head: 1.23 W/kg; Body-worn: 0.401 W/kg
PCS mode (Part 24):
Head: 1.44 W/kg; Body-worn: 0.596 W/kg
